Abstract

The invention discloses a special cleaner for a molten iron ladle furnace liner and a using method thereof. The cleaner comprises the following raw materials in percentage by weight: 35-40% of pre-melting materials, 23-27% of fluxing agents, 9-11% of calcite powder and 6-8% of soda-lime glass. The special cleaner for the molten iron ladle furnace liner can be used for removing slag of molten iron ladles; meanwhile, the special cleaner is high in melt performance, stable in slag removal effect, low-cost and easily available in preparation raw materials, free of other peculiar smells after put into a working furnace, environmentally-friendly in way and free of influence on the operation environment; the quality of the molten iron is improved; the high-quality raw materials are directly provided for subsequent processes; the subsequent melting processes are eliminated; the processing cost is reduced; the corresponding fees are reduced; the green production standard can be met.

Description

technical field [0001] The invention relates to the field of metallurgical auxiliary materials, in particular to a special cleaning agent for ladle furnace lining and a using method thereof. Background technique [0002] The cleaning agent is mainly used to remove impurities in molten iron in the foundry industry. It can gather insoluble matter on the surface of the molten iron solution to make it easy to remove and ensure the purity of the molten iron solution; it can also be used as a high-quality thermal insulation covering agent and slag blocking material. Excellent insulation layer and excellent slag blocking performance, and can effectively isolate the air to prevent the secondary oxidation of the iron solution. [0003] The molten iron contains a variety of harmful gases and non-metallic inclusions. On the one hand, scrap iron added, returned materials without shot blasting, oxide slag that is easy to form during smelting, and on the other hand, the stirring generated...
